The Rovner Versa Ligatures are designed as replacement for the Eddie Daniels ligatures. They are designed to have exceptional control especially at loud volumes. They also come equipped with an adaptable pressure plate system capable of six different tones.

This will improve the sound of any mouthpiece. It gives you great projection &amp; the flexibility to brighten or darken the sound. I use mine on a Ria metal mouthpiece on my Selmer Balanced Action alto. Great sound, projection. I couldn't ask for more (the rest is up to me). This is definately worth trying out; you'll likely love it..... I have 3 of these (soprano, alto, tenor) &amp; have had no problems with any of them.
